Both of the remote keys provided with the vehi-
cle have the keyless function, and additional
remotes can be ordered. The system can
accommodate up to six keyless drive remote
keys.
NOTE
The number of doors that are unlocked at
the same time can be set in the Personal
settings menu, see page 83 for additional
information.
Unlocking the vehicle
•A keyless drive remote key must be on the
same side of the vehicle as the door to be
opened, and be within 5 feet (1.5 meters)
of the lock or the trunk opening control (see
the shaded areas in the illustration).
•Pull a door handle to unlock and open the
door or press the trunk opening control.
•See page 148 for information on starting a

Alarm*

The alarm system
The alarm is automatically armed whenever the
car is locked with the remote key, or if a front
lock button is depressed.
When armed, the alarm continuously monitors
a number of points on the car. The following
conditions will trigger the alarm:
•The hood is forced open.
•The trunk is forced open.
•A door is forced open.
•The ignition switch is tampered with
•An attempt is made to start the car with a
non-approved key (a key not coded to the
car's ignition).
•If there is movement in the passenger com-
partment (if the car is equipped with the
optional movement sensor).
•The car is lifted or towed (if the car is equip-
ped with the optional inclination sensor)
•The battery is disconnected (while the
alarm is armed).
•The siren is disconnected when the alarm
is disarmed.
The alarm indicator light
G020227
Alarm indicator light
The status of the alarm system is indicated by
the indicator light on at the top of the dash-
board (see the illustration):
•Indicator light off – the alarm is not armed
•The indicator light flashes every two sec-
onds – the alarm is armed
•The indicator light flashes rapidly before
the ignition is switched on – the alarm has
been triggered. The message
ALARM
TRIGGERED, CHECK CAR will also be
displayed.
•Fault in the alarm system: If a fault has
been detected in the alarm system, a mes-
sage will be shown in the information dis-
play. Contact your Volvo retailer to have
the alarm system inspected and repaired if
necessary.
Arming the alarm

Press the LOCK button on the remote key,
or press the central lock button on one of
the front doors with the door open. One
long flash of the turn signals will confirm
that the alarm is armed.
Disarming the alarm

Press the UNLOCK button on the remote
key or insert the key in the ignition1 to dis-
arm the alarm. Two short flashes from the
car's direction indicators confirm that the
alarm has been deactivated and that all
doors are unlocked.
1On vehicles with the optional keyless drive, press in the start control in the ignition switch.

Economical driving conserves natural
resources
Better driving economy may be obtained by
thinking ahead, avoiding rapid starts and stops
and adjusting the speed of your vehicle to
immediate traffic conditions.
Observe the following rules:
•Bring the engine to normal operating tem-
perature as soon as possible by driving
with a light foot on the accelerator pedal for
the first few minutes of operation. A cold
engine uses more fuel and is subject to
increased wear.
•Whenever possible, avoid using the vehicle
for driving short distances. This does not
allow the engine to reach normal operating
temperature.
•Drive carefully and avoid rapid acceleration
and hard braking.
•Use the transmission's Drive (D) position
as often as possible and avoid using kick-
down.
•Do not exceed posted speed limits.
•Avoid carrying unnecessary items (extra
load) in the vehicle.
•Maintain correct tire pressure. Check tire
pressure regularly (when tires are cold).
•Remove snow tires when threat of snow or
ice has ended.
•Note that roof racks, ski racks, etc,
increase air resistance and also fuel con-
sumption.
•At highway driving speeds, fuel consump-
tion will be lower with the air conditioning
on and the windows closed than with the
air conditioning off and the windows open.
•Using the onboard trip computer's fuel
consumption modes can help you learn
how to drive more economically.
Other factors that decrease gas mileage
are:
•Dirty air cleaner
•Dirty engine oil and clogged oil filter
•Dragging brakes
•Incorrect front end alignment
Some of the above mentioned items and others
are checked at the standard maintenance
intervals.
WARNING
Driving with the trunk open: Driving with
the trunk open could lead to poisonous
exhaust gases entering the passenger com-
partment. If the trunk must be kept open for
any reason, proceed as follows:
1. Close the windows.
2. Set the ventilation system control to air
flow to floor, windshield and side win-
dows and the blower control to its high-
est setting.
Weight distribution affects handling
At the specified curb weight your vehicle has a
tendency to understeer, which means that the
steering wheel has to be turned more than
might seem appropriate for the curvature of a
bend. This ensures good stability and reduces
the risk of rear wheel skid. Remember that
these properties can alter with the vehicle load.
The heavier the load in the cargo area, the less
the tendency to understeer.

more frequently and spray an anti-rust oil
on the battery posts.
•Volvo recommends the use of snow tires
on all four wheels for winter driving – see
the chapter "Wheels and tires."
•To prevent the washer fluid reservoir from
freezing, add washer solvents containing
antifreeze (see page 217 for the location of
the washer fluid reservoir). This is impor-
tant since dirt is often splashed on the
windshield during winter driving, requiring
the frequent use of the washers and wip-
ers. Volvo Washer Solvent should be dilu-
ted as follows: Down to 14 °F (–10 °C):
1 part washer solvent and 4 parts water
Down to 5 °F (–15 °C): 1 part washer sol-
vent and 3 parts water Down to 0 °F
(–18 °C): 1 part washer solvent and 2 parts
water Down to –18 °F (–28 °C): 1 part
washer solvent and 1 part water.
•Use Volvo Teflon Lock Spray in the locks.
NOTE
Avoid using de-icing sprays as they can
cause damage to the locks.
Conserving electrical current
Keep the following in mind to help minimize
battery drain:
•When the engine is not running, avoid turn-
ing the ignition key to position II. Many
electrical systems (the audio system, the
optional navigation system, power win-
dows, etc) will function with the ignition key
in position I. This position reduces drain on
the battery.
•Please keep in mind that using systems,
accessories, etc that consume a great deal
of current when the engine is not running
could result in the battery being completely
drained.
•The optional 12 volt socket in the trunk
(certain models only) provides electrical
current even with the ignition switched off,
which drains the battery.
NOTE
•If the ignition is switched on, a warning
message will be displayed in the text
window in the instrument panel when
the battery charge is low.
•An energy conserving function
designed into the vehicle's electrical
system will switch off certain functions
or reduce the load on the battery by,
e.g., reducing the audio system's vol-
ume.
Before a long distance trip
It is always worthwhile to have your vehicle
checked at a trained and qualified Volvo serv-
ice technician before driving long distances.
Your trained and qualified Volvo service tech-
nician will also be able to supply you with
bulbs, fuses, spark plugs and wiper blades for
your use in the event that problems occur.
As a minimum, the following items should be
checked before any long trip:
•Check that engine runs smoothly and that
fuel consumption is normal.
•Check for fuel, oil, and fluid leakage
•Have the transmission oil level checked2.
•Check condition of drive belts.
2To prevent injury from contact with hot surfaces, do not inspect your vehicle's transmission fluid yourself. Have your vehicle's transmission fluid level inspected by a qualified Volvo service technician.
